FISH-CLEANING MACHINE.

SPECIFICATION forming part of Letter: Patent No. v'774,6'74, dated November 8i, 1904.

Application iilsd March 28,1903.

To all whom, it ntctg/ concern:

Be it known that I, JOHN KELLINGTON, a citizen of the Dominion of Canada, residing at New Westminster, in the Province of British Columbia, Canada, have invented a new and .useful Improvement in Fish-Cleaning Machines, of which the following is a specification.

My invention relates to a machine for cleaning fish, and is a modification and improvement on that for which an application for a patent was filed by me on the 6th of kMay, 1902, under Serial No. 106,154.. Several of the fea` tures revealed and claimed in that application are embodied in the presentmachine, while others are slightly modified.

rl`he general idea of drawing the fish by the tail through the several operations of splitting, gutting, scrubbing, and washing without other support than thatof the operative mechanism is retained in the present machine, but the reciprocating bar by which the iish'was carried is `replaced by an endless' drag-chain provided at intervals with gripping devices, each of which as it comes around to the entering end of the machine automatically seizes a [ish by the tail and draws it through. By this change I am enabledtoshorten the machine considerably, while the continuous succession in which the fish pass through the cleaning operation permits an increased output to be obtained.

My improvements are furthervdirected to provide a more positive and efiicient tail-grip and a more uniform and thorough means for removing the viscera and scrubbing and wash-V ing the outside and inside of the fish.

There are also several minor points of improvement whichwill be specifically drawn attention to and described.

The construction and operation of the machine are fully described in the following specification and illustrated in the drawings which Figure 1 is a side elevation of the machine;

Fig. 10 is a perspective of the means for effecting the release of the tail-cutting-lnife mechanism.

The frame of the machine consists of parallel sidemembers 2, suitably supported at a convenient height for the operator, and forms abed to which the various'mechanisms are secured, the driving-gear being on a frame 3,

fastened across the side frames at the end of the machine opposite to where the lish are entered. .f

The endless chain 4, by which the iish are dragged through the machine, is carried by the chain pitch-wheels 5, 6, and 7, 5 and 6 8O being at the entering end and 7, the driver, on the first-motion shaft 108 at the other end.

The return-chain is supported by an idler 8, the standard 9 of which, being vertically adjustable, enables it to serve also asa tightener.

The drag-chain 4 is provided at suitable intervals with tail-gripping devices secured toA it, each comprlsmg (see Fig. 3) a guide portion 10, by which the attachment to the chain of the Xed arm, is a bolt 14, having a jaw member 15 to correspond with l2, and this jaw member is provided with pointed pins 16, which enter, when the Jawsare closed, corre- Fig. 6o

Fig. 9 is a cross- 65 sponding apertures or a slot 12 in the fixed l jaw member.

To support the grip devices under the lateral strain imposed by the drag of the fish, the guide portions 10 slide in the grooved guides 20, which extend between the extremes of the working movement of the chain, the lower bar of the guides being downwardly flared, as 20, at the front end to facilitate the entrance of 10. (See Fig. 4.) The slidable bolt 14 is produced at the opposite end to the jaw through the guide 13 and bears against a bar 21, secured to the sprocket-wheel standards 19 or otherwise suitably supported. At

the entering end of the machine this bar is.

provided with an incline 21, by which the bolt is forced in and the jaws 15 and 12 closed on one another, and is extended throughout the working limit of the chain, so that the tail of a fish being gripped the hold is maintained until the tail has been severed and it is desired to remove it. Having passed the end limit of the bar 21, the release of the tailgrip is effected by means of the upper edge of the curved plate 22,(see Figs. 2 and 5,) which is secured to the cross-frame 3 at the farther end of the machine and, projecting upward into the path of the tail-grip, engages a projection 17 of the bolt and draws it open. As

soon as the jaws 12 15 are opened slightly the.

point of the hook member 23 is engaged and by the further movement of the grip forces the severed tail from off the pins 16. The grips, with the jaw members open, then pass with the chain 4 over the driving-sprocket and back to the entering end of the machine. A light spring 18, secured to the outside of the belt-guide 13 and bearing against the side of the bolt, serves to prevent the jaws from shaking together during the return movement of the chain. This spring 18 is shown on the back of the grip, but will preferably be on the front side of it.

As in the previous machine, the fish to be cleaned is placed by the operator in a receiving-holder 26 belly down and tail first, (see Fig. 6,) the tail being supported by a portion 27 at the end of a lever 28, hinged to the crossframe of the machine adjacent to 26 in such a manner that it can be lifted up so as to bring the fluke of the tail into the path of the gripping devices which pass above it. The elevation of the tail-lever into the path of the grip and its subsequent depression is effected through a series of levers actuated by the passage of the tail-grip members on the dragchain. The elevation is performed by the grip in advance of the one which is to carry the fish in the holder, the portion 13 of the grip engaging and moving over an upwardlyprojecting lever 30, which lever is secured to a short shaft 31, mounted in bearings on the top of the side frame 2 of the machine, which shaft 31 has secured to its opposite end a short lever 32, which is connected by a rod 33 to a downwardly-projecting lever 34, fastened to a short shaft 35, mounted in bearings on the side frame 2, adjacent to the tail end 27 of the fish-holder, and on the opposite end of this shaft 35 is a short upwardly-projecting lever 36, having a laterally-projecting pin 36, designed to engage the front side of a bent lever 37, mounted free on a short shaft or pin 38, secured to the under side of the side frame and having a short backward projection 39 approximately at right angles to it. This projection 39 bears on the upper side of a lever 40, mounted free on a pin or short shaft 41, secured to the under side of the side frame and is laterally secured to a curved cam-shaped lever 42, on which the tail-lever of the fish-receptacle rests. Thus as the lever 30 is moved forward' by the advance of the grip (see dotand-dash lines in Fig. 6) the lever 32 is moved in the same direction, and by means of the connecting-rod 33 the downwardly-projecting lever 34 is correspondingly moved forward. The upwardly-projecting lever 36, secured to the same shaft 35, is therefore moved backward. The laterally-projecting pin 36a of this lever bearing on the forward side of the lever 37 carries the latter backward with it, and the projection 39 is depressed on the lever 40, correspondingly elevating the camshaped lever 42 under the fish-holder lever 28, and the tail end is thus lifted up to the desired height to be in the path of the grip-jaws 12 15. The tail end of the cradle being elevated and the tail of the fish in it seized by the grip, the upwardly-bent end 37a of the lever 37 is engaged by the edge 14u of the grip-bolt and, acting through the lever system previously described, the fish-holder is lowered and the lever system restored to the operative position ready for the next elevation. A spring 43, (see Fig. 63,) having a V-shaped end43, is secured to the standard 19, engages the eye of the rod 33 in its attachment to the lever 34, and maintains the lever system in one position or the other, as required.

The head-cutting mechanism is the same as 4in the previous machine, being operated by gill-levers 45, which are situated on each side of the fish-holder lever and are shaped to catch and hold the head by the gills while the body of the fish is being drawn forward, the operation being rendered more certain by the effect of an upwardly,-inclined member 29, situated just in advance of the fish.- holder member 26 and just over the joint-pin of the tail-elevating lever 28. This member b v holding up the head of the fish by the chin while the body is crowded down on the lever 28 opens of the gills of the fish and insures them being caught by the gill-levers. At the end 'of 29 side portions 29a prevent the recoil of the gill-lever spring carrying skin, zsc., between the member 29 and the lever 28.

The gill-levers 45 are, as in the previous application referred to, loosely mounted on IIO -venicnt rotating shaft.

the shaft 47 by pins 46, so as to have a free pivotal movement on them, but secured against turning on the shaft. An adjustable coilspring -48 presses the upper ends of the lever together, the distance apart being limited by an adjusting-screw 49 and the movement rela- Itive to one another centralized by the diagonal link 50.

In order to insure that the back of the gills is the determining-point for the position of the decapicating-cut, I form the cross-section of the levers (see Fig. 6b) with a recurved outer edge 45, against which the edge of the gills catches and by which the levers 45 are pulled over against the resistance of the spring 51, releasing the vlatch and permitting the knife 52 to be operated by the rotation of the shaft 53. The mechanism which effects this release and action is identical with what is in my previous application and need not be further described. f

In order'to free the gill-levers 'from tight contact on the body of the fish until the tailgrip is secured, their inner sides (see Fig. 7) have a curved projection 45h, designed to. be engaged by the width of the elevating-lever 42, whereby while the fish-holder is in the elevated position the gill-levers are spread; but as soon as the fish-holder is lowered and the head approaches the gill-levers they are closed together tothe required width to engage the gills, whichwidth is adjustable to the requirements of the size and condition of the fish being cleaned by the adjusting-screw 49, before referred to. v

After the removal of the head the belly of theiish is split and the viscera removed. The splitting is accomplished (see Figs. 8, 9) by a semicircular oscillating knife 56, supported in suitable bearings 57, just in advance of thev end of the fish-holder, and the movement is imparted to its shaft 55 by ashort arm=58 and a connecting-rod 59 from a crank on a con- Just ahead of the knife 56 is a conical quick-pitch screw 60, secured to the end ofand rotatable at a high rate of speed by a shaft 61 in a bearing 62. The axis of rotation of this shaft isin the middle line of the machine, but inclined at such an angle that the upper edge of the tapered thread of the screw 60 is in a line parallel to the path of the drag-chain 4. The

shaft 61 is rotated by bevel-pinions from a cross-shaft 63 at the end of the machine. This screw60 opens the split of the belly and removes the cntrails as the fish is dragged over it. f l

To press the body of the lish down on the splitting-knife and to maintain it in the proper position under the turning tendency of the rapidly-rotating screw, a series of back and breast rollers 66 and 70 are provided. The former are grooved to the yapproximate cross-section of the back of the fish and are free torotate on spindles 66 at the lower end of the arms 67,

which are pivotally mounted and partially counterbalaneed by adjustable weights 68, -so as to bear down on the passing fish and rise and fall as occasion may require. They are lifted to permit the passage of the tail-grip by the cam-like conformation of the carryingarms 67, which are engaged by the edge 11EL of the tail-grip member as it approaches each one.

As the guide portion 10 of the grip is not in the guide-grooves 2O when the first back roller 65a is encountered the normal position of this one is up out of action, and it is allowed to fall into operativecontact by an arm 69, which extends under the spindle 66 of the second roller, so that as the second one is lifted the first one is allowed to bear down on the fish.

rThe breast-rollers 7 0 are flattened cones rotatable on spindles 71, which are adjustable in their brackets by the screw 72 and so placed that the lower conical face bears against the side of the passing fish and opposes the turning effort of the viscera-removing screw 60.

Slidable on the shaft 61 of the screw 60 and close up to the bearing 62 is a scrubber 75, havinga series of ridges 76, the shape of which conforms approximately to the cross-section of the intestinal cavity. This scrubberhas a rapid endwise-reciprocating movement imparted to it from a small crank 78 by the connecting-rod 77, and parallel to the screw-shaft 61 and extending close up to the butt-end of -the screw is a water-service pipe 79, having a series of perforations 80 along its upper sur' face. The pipe passes through the ridges of the scrubber, which is slidable loosely on it as it reciprocates. The action of `this scrubber is to clean the intestinal cavity, the ridges 76 scraping away the slimy skin and blood` which cling around the backbone of the iish, and the water-spray from the perforations 8O washes it away.

Just above the reciprocating internal scraper is rotatably mounted on a swinging frame 81 a back-scrubber constructed of a number of pieces 83, of flexible canvas-rubber, secured to a bladed wheel 82. The pieces 83 are shaped to conform somewhat to the cross-section of a fish s back, and the wheel is rotated at a moderately high rate of speed by a light chain 84 over a pinion 85 on the scrubber-shaft 86 from a chain pitch-wheel 87, keyed on a shaft 88, which also forms the pivot about which the scrubber-frame swings. The'weight of the scrubber and itsframe is partially counterbalanced by a coil-spring 89, and the frame is lifted and held out of use when no fish is under it by a lever 90,'secured to a shaft 91, at the other end of which is secured another IOO lever 92, projecting in the path of the tailgrips, which as they bring. a [ish forward depress the lever 92 and by withdrawing the lever 90 from the support of the scrubberframe 81 allow the scrubber vto be lowered ISO onto the passing sh. The bent extension 92EL to the lever 92 permits the yscrubber to lie on the sh while the average length of fish is passing under it, and the lever system has a counterweight on a lever 94 to raise the scrubber out of action as soon as the grip is disengaged from 92u.

A jet of water from a service-pipe 93 is directed on the center of the scrubber to facilitate the washing, and a light casing (not shown) incloses the scrubber to prevent the spray being scattered. This finishes the cleaning process, and it only remains to cut the fish from the tail in the grip. This is performed by a knife,54, operated from the shaft 53 in the same manner as the headknife. rlhe release mechanism is, however, brought into play in a different manner.

In advance of the scruhbers a sufficient distance to insure that the fish is clear of it a short lever 95 projects upwardly in the path of the tail-grip member 14. The lever is secured to a short shaft 96 in bearings 97 on the side frame 2, and at the outer` end of this shaft 96 an arm or lever 98 is secured, having a detent meinber- 99 pivotally mounted on a pin 100 in the end of 98, so as to be susceptible of lateral movement against the resistance of a fiat spring 101, secured to the lever 98 and bearing against the detent member 99. The detent 99 engages the pin 102a of the rod 102, which effects the release of the knife-operating mechanism, and this having been effected and the knife fallen the detent is thrown out of engagement with the pin 102 by the incline 103 forcing the detent-piece 99 laterally and off the pin 102, the detent-piece moving on the hinge-pin 100 against the resistance of the spring 101. The detent-piece 99 is provided with an upwardlyturned end 99 to prevent it getting over the pin 102 and to the under side of it. A coilspring 73, between a tail end`98 of the lever 98 and a pivotally-mounted lever 7 4, the end of which bears against the lower end of the rod 102, maintains the system in the normal position; and a stop 64, secured on the shaft 96, determines such position. The detent is disengaged from the pin in this manner, so that the tail-cutting knife having once delivered its blow, been disengaged from the operating-gear, and recovered by its spring, the rod 102, which controls the knife-operating mechanism, may be free to return and sustain it out of action until the next tail-grip again releases it.

The general means of operating the several shafts is not material to this application,

`but is indicated in Figs. 1 and 2, 105 being the pulley on the first motion-shaft 104, driven by a belt from apower source exterior to the machine, and a sprocket-wheel 106 on this shaft drives a chain 107, passing over a sprocket-wheel on the shaft 88 for the eX- ternal scrubber, and another on the shaft 108, on which is the chain-wheel 7, which drives the drag-chain 4. The screw-shaft 61 is driven by bevel-gears from a cross-shaft 63, which is driven by a chain 109 from the shaft 88, which chain also drives the shaft on which is the crank 7 8, which operates the visceral scrubber 7 5. The splitting-knife is operated by a crank on the end of the cross-shaft 63, and the shaft 53, which actuates the head and tail cutting knives, is driven by bevel-gears from the first motion-shaft 104.

The machine is further provided with the necessary separate hoppers and chutes for receiving the offal and the cleaned fish and conveying the same away.
